if two equal charges , each of 1c,were separated in air by a distance of 1km,what would be the force between them?

An electric charge q caused an electric potential of V = -218 V at point A 10.6 m from q. What is the electric charge q?

A cargo was dropped down a helicopter which hovered at height of h=125m

When will the cargo reach the land?free fall acceleration is g=10m/s2.Air resistance must be ignored

On a surface of a planet, 60 J of work is done against gravity to raise a mass of 2.0kg through a height of 10m. Determine the gravitational field strength g on this planet

The Sun has a radius of 6.9599× 10 8 m. Use the mass of the Sun from your data

booklet to calculate the gravitational field strength at the surface of the Sun.
